Description

Table leg

Technical Field

The invention relates to a table leg, in particular to a table leg which is provided with a hollow leg post, is supported by an adjusting leg base without sinking, is supported by the inner part and the outer part of the adjusting leg base without bending, and is convenient to adjust and stable in contact with the ground.

Background

When the inclined table legs of a common table are placed on the ground to form instability, the height difference of each table leg is easy to appear, and most people can adjust the height of each table leg on the two sides of the bottom surface of the table by using paper or paperboard for padding. Further, referring to fig. 1A and 1B, the workshop industry aims to solve the problem that the inclined table legs of the table are easy to generate height difference after being placed. Therefore, in order to enable the height of each inclined leg 11 of the table 1 and the ground to generate stability, a plastic sleeve 12 is respectively and additionally sleeved at the tail end 111 of each inclined leg 11 of the existing table 1, each plastic sleeve 12 can protect the tail end 111 of each inclined leg 11, but because the inside of each inclined leg 11 is hollow, no support is arranged inside the tail end 111 of each inclined leg 11, when each plastic sleeve 12 at the tail end 111 of each inclined leg 11 is in contact with the ground, after a long time of use, each plastic sleeve 12 is pressed and worn for a long time due to the weight of the table 1, and the instability of each inclined leg 11 after being placed is influenced. Moreover, after each plastic sleeve 12 is worn and thinned, the end 111 of each inclined leg 11 opposite to the thinned portion of each plastic sleeve 12 is also worn and recessed or deformed (as shown in fig. 1C), which results in instability when each inclined leg 11 is placed on the ground.

The present inventor has solved the above-mentioned disadvantages of the conventional tilt table legs 11 with each plastic cover 12. Therefore, the inventor has studied the structure of the combined desk leg of the office desk of the second taiwan patent publication No. M243990 in the prior art again, please refer to fig. 2, in which a plastic sleeve 21 is sleeved on the inner edge of the lower portion of the desk leg 2, the plastic sleeve 21 is disposed on the inner edge of the lower portion of the desk leg 2, and the desk leg 2 overcomes the disadvantages of abrasion and depression caused by long-term pressing due to the fact that the inner edge of the lower portion of each inclined desk leg 11 has no support and is subjected to the weight of the desk 1. Therefore, the inner edges of the upper and lower sections of the plastic sleeve 21 are provided with an internal thread 211, and a supporting base 3 is matched with the internal thread 211, wherein the upper section of the plastic sleeve 21 is sleeved towards the inner edge below the table leg 2, so that the lower part of the table leg 2 is abutted against the upper part of the lower section of the plastic sleeve 21, the supporting base 3 is provided with a main body 31 and a base 32, the outer edge of the main body 31 is provided with an external thread 311 which forms a threaded connection with the internal thread 211 of the inner edge of the plastic sleeve 21 below the table leg 2, so that the main body 31 and the table leg 2 can be mutually screwed together.

As mentioned above, the plastic sheath 21 and the supporting leg base 3 installed below the table leg 2 in the second prior art can not only find the uneven or inclined condition with the ground when the table leg 2 is movably adjusted, but also adjust the length of the main body 31 of the supporting leg base 3 and the angle of contact with the ground, and improve the defect that the tail end 111 of each plastic sheath 12 and each inclined table leg 11 in the prior art is worn. On the other hand, in the second prior art, the bottom end of the main body 31 is provided with a connection portion 312 having a spherical shape, and the top surface of the base 32 is provided with a recess 321 capable of being matched with the connection portion 312, so that the base 32 can be sleeved on the connection portion 312 at the bottom end of the main body 31 by using the recess 321 and can freely rotate within a certain range. However, the table leg 2 of the second prior art has the following disadvantages after being used:

1. because the structure of the table leg 2 is complex, and the connecting portion 312 of the main body 31 is used as a universal joint, after the connecting portion 312 is used for a long time, the universal lubrication of the connecting portion 312 is not only ineffective, so that the connecting portion is not easy to rotate, or dirt is easily stuck at the connecting portion 312, so that the universal rotation of the connecting portion 312 is damaged.

2. Because the main body 31 is hollow inside and weak in strength, the external thread 311 is easy to deform in the screwing process, and when the rotatable length of the external thread 311 enters the inside of the internal thread 211 of the plastic sheath 21 below the table leg 2 too much if the external thread is rotated too much, the stress borne by the table leg 2 is relatively good, but as shown in fig. 3A, when the exposed distance H1 of the external thread 311 of the main body 31 is too short, the table leg 2 bears the gravity of the table top for a long time and presses down, so that the joint 3111 between the external thread 311 of the main body 31 and the internal thread 211 of the plastic sheath 21 is easily locked, if the table leg 2 is found to be unstable in placement, the hand of the hand facing the universal joint 312 is difficult to stably hold, or the hand adjusts the external thread 311 of the main body 31 to withdraw from the plastic sheath 21 and rotate, since the connection portion 3111 between the external thread 311 and the internal thread 211 is blocked, it is not easy to adjust the external thread 311 of the main body 31 to withdraw outwards.

3. If the rotatable length of the external thread 311 of the main body 31 is rotated into a little, the rotatable length of the external thread 311 of the main body 31 is more toward the outside of the internal thread 211 of the plastic sheath 21 below the table leg 2, although the external thread 311 can be conveniently held by the hand of the user and rotatably adjusted from the inside of the plastic sheath 21, when the table leg 2 is pressed down by the gravity of the table top for a long time, not only the end of the table leg 2 is not well stressed, but also the exposed distance H2 of the external thread 311 is too long, and the connection end 3112 between the external thread 311 of the main body 31 and the internal thread 211 of the plastic sheath 21 is pressed down by the gravity of the table top (as shown by the arrow in fig. 3B), the main body 31 has no support inside and outside, so that the main body 31 is deformed upward from the exposed distance H2 of the connection end 3112 between the external thread 311 and the internal thread 211 (as shown in fig. 3B), the deformed external thread 311 is not easy to rotate into the internal thread 211 of the plastic sleeve 21 below the table leg 2, which is not beneficial to the support below the table leg 2, and further causes stress to concentrate on the external thread 311 and the end of the plastic sleeve 21, which is easy to damage, and is not beneficial to the support below the table leg 2, thereby increasing the elimination of the table leg 2 without end, and causing the cost consumption of the user.

4. Since the plastic sheath 21 under the table leg 2 is easily deformed due to thermal expansion and contraction, the external thread 311 of the main body 31 is not easily rotated toward the inside of the deformed internal thread 211 of the plastic sheath 21, and the usage adjustment is not optimal.

The hollow leg 5 is a hollow tube, the hollow leg 5 has a joint end 51 combined with the bottom surface of the table 7 and a butt end 52 opposite to the joint end 51, the butt end 52 has at least one spiral point 53 on at least one side and in the inward direction, and the spiral point 53 is punched from the outside to the inside of the butt end 52 to be recessed inward.

Referring to fig. 4B to 5B, the adjusting base 6 includes an outer base 61 and a screw portion 62 fastened to the bottom end of the outer base 61. The outer housing 61 has an opening 611 at one end, a hollow chamber 612 inside and communicating with the opening 611, and a closed end 613 opposite to the opening 611.

The screw portion 62 is solid, and the strength of the screw portion 62 is sufficient. The screw-connection portion 62 is screwed into the hollow socle 5 by matching the screw point 53 of the abutting end 52, and the screw-connection portion 62 is provided with a plurality of turns of screw concave sections 621 by matching the screw point 53 of the abutting end 52 from the top to the bottom outer periphery, and an engagement section 622 is extended from the ends of the screw concave sections 621, the engagement section 622 and the inner edge 6121 at the bottom end of the hollow accommodating chamber 612 of the outer base body 61 form a tight fit, so that the engagement section 622 of the screw-connection portion 62 is inserted toward the opening 611 of the outer base body 61, after the engagement section 622 and the inner edge 6121 at the bottom end of the hollow accommodating chamber 612 form a tight fit, a gap 63 is formed between the outer diameter of the screw concave sections 621 of the screw-connection portion 62 and the inner diameter of the outer base body 61, so as to provide for the abutting end 52 of the hollow socle 5 to be inserted. When the thread concave sections 621 of the screw connection portion 62 are screwed in from the abutting end 52 of the hollow leg post 5, the thread concave sections 621 are screwed in the abutting end 52 along the track of the screw point 53 of the abutting end 52 to be fastened so as to achieve positioning or screwing-out displacement, so that the abutting end 52 of the hollow leg post 5 is supported by the screw connection portion 62 as a solid body and is not recessed, and is supported by the screw connection portion 62 as a solid body and the outer seat body 61 as an outer part and is not bent, and then the outer seat body 61 is completely covered on the outer side of the abutting end 52 provided with the screw point 53, so that the overall appearance of the hollow leg post 5 is excellent.

Moreover, the length of the outer seat 61 of the adjusting foot seat 6 is sufficient to cover the screw point 53 of the abutting end 52 of the hollow leg 5.

More specifically, in the gap 63 between the screw portion 62 and the outer seat 61, the outer diameter of the joint portion 622 is larger than the outer diameter of the screw portion 62, and the outer diameter of the screw portion 62 is smaller than the inner diameter of the hollow chamber 612 of the outer seat 61, so that the abutting end 52 of the hollow leg 5 is inserted into the gap 63.

In view of fig. 4A and 4B, the number of the spiral points 53 is preferably two opposite to each other on the average four sides and in the inward direction toward the abutting end 52 of the hollow leg 5.

Referring to fig. 4A to 5A, with the structure described in the previous section, when the joint end 51 of the hollow leg post 5 of the table leg 4 of the present invention is respectively combined with two sides of the bottom surface of the table 7, and the abutting end 52 of the hollow leg post 5 is assembled with the adjusting leg base 6, the joint section 622 of the screw portion 62 is tightly fitted with the inner edge 6121 at the bottom end of the hollow accommodating chamber 612 of the outer base body 61, and then the screw portion 62 of the adjusting leg base 6 is inserted into the abutting end 52 of the hollow leg post 5, the screw concave sections 621 of the screw portion 62 are screwed into the abutting end 52 along the track of the screw point 53 of the abutting end 52 to be fastened so as to be positioned or screwed out to be displaced, at this time, the abutting end 52 of the hollow leg post 5 is gradually positioned towards the gap 63, and then the outer base body 61 is completely covered on the outer side of the abutting end 52 where the screw point 53 is provided, so as to quickly assemble the table legs 4 on the bottom surface of the table 7.

Referring to fig. 5A and 5B, the table leg 4 assembled to the bottom surface of the table 7 according to the present invention is placed on the ground, when the table leg 4 is pressed by the gravity of the table top for a long time, and it is found that the table leg 4 is not stably placed on the ground, the height of the adjusting foot seat 6 can be gradually adjusted, and then, as shown in fig. 5C, if the adjusting foot seat 6 is screwed inward toward the lower side of the abutting end 52 of the hollow leg post 5, the threaded concave sections 621 of the threaded section 62 are screwed in along the spiral point 53 protruding inside the abutting end 52, so that the distance h1 between the end of the hollow leg post 5 of the table leg 4 and the bottom end of the adjusting foot seat 6 is shorter, and the outer seat 61 covers the abutting end 52 and the outer sides of the threaded concave sections 621, if the outer seat 61 and the joint section 622 are worn away, the abutting end 52 of the hollow leg post 5 is not supported by the threaded section 62, wherein the outer housing 61 and the engaging section 622, if ground away, are also ground up to the end of the threaded concave sections 621, as shown in fig. 5C.

Referring to fig. 5D, when the adjusting leg 6 is adjusted to rotate outward toward the lower side of the hollow leg 5 and withdraw, the concave sections 621 of the screw portion 62 can rotate outward along the screw point 53 protruding from the abutting end 52, so that the distance h2 between the end of the hollow leg 5 of the table leg 4 and the bottom end of the adjusting leg 6 is longer, the abutting end 52 of the hollow leg 5 is supported by the screw portion 62 inside and the outer seat body 61 outside, the abutting end 52 of the hollow leg 5 is not bent, the concave sections 621 of the adjusting leg 6 are also protected from being covered by the outer seat body 61 when rotating outward and withdrawing, the concern of upward bending deformation caused by the downward force of the desktop gravity is avoided, and the abutting end 52 below the hollow leg 5 of the table leg 4 is surely adjusted to be stably placed on the ground, is quite favorable for supporting the lower part of the table leg 4, so that the usability of the table leg 4 is high.

As mentioned above, the table leg 4 of the present invention has a very good supporting force and structural strength, so that when the table leg 4 is found to be uneven with the ground, the adjusting foot seat 6 can be slightly adjusted, and the screw portion 62 can support the inside of the abutting end 52 of the hollow leg post 5, so that the abutting end 52 of the hollow leg post 5 will not be sunk, and the abutting end 52 of the hollow leg post 5 is supported by the screw portion 62 inside and the outer seat body 61 outside, so that the abutting end 52 of the hollow leg post 5 can not be bent, and the stability of placing the abutting end 52 on the ground is good, thereby obtaining the best supporting effect.

As shown in fig. 5A to 5D, it is clearly and obviously found from the above descriptions that, the present invention can be completely screwed into the abutting end 52 under the hollow leg 5 through the screwing part 62 of the adjusting foot 6, and the abutting end 52 is positioned towards the gap 63 between the screwing part 62 and the outer seat body 61, and then the outer seat body 61 is completely covered on the outer side of the abutting end 52, so as to prevent the abutting end 52 and the thread concave sections 621 from being pressed down and depressed or bent and deformed for a long time due to the weight of the table 7, and the adjusting foot 6 under the table foot 4 is contacted with the ground to be stable, so as to not only easily adjust the length of the table foot 4, but also to improve the connection point 3111 between the external thread 311 and the internal thread 211 of the table foot 2 structure in the prior art to form a jam, which is not easy to adjust the external thread 311 of the main body 31 and not easy to be rotated out of the sleeve body 21, and the screw connection of the external thread 311 of the main body 31 and the internal thread 211 of the plastic sheath 21 is too late or too late, which may affect the end of the table leg 2 to bear enough or not enough force, even the external thread 311 is pressed by the gravity of the table top, so that the exposed distance H2 of the connection end 3112 between the external thread 311 and the internal thread 211 is too long and may be bent upwards, and the bent external thread 311 will not rotate into the internal thread 211 of the plastic sheath 21 below the table leg 2, which is not conducive to the support below the table legs 2 in the prior art, and even increases the elimination of the table legs 2 in the prior art. Therefore, the assembled structural strength and easy adjustment of the table legs 4 of the present invention can also completely meet the requirements of users.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore intended that all such changes and modifications as fall within the true spirit and scope of the invention as defined by the appended claims be interpreted in accordance with the breadth to which they are fairly, if not explicitly recited herein.
